Beit known that I, ALFRED RAsMnS- SEN, a 'citizen ofthe United States,'res1d1ng atWValnnt, 'in the county of Pottawattamie and State of "Iowa, "have .invented certain new. and useful Improvements lin Oil Gauges, of which fthe following is a specification, reference 'being had to the accompanying drawin s.

('iihi's invention lrelates tro-gauges and` particularly 'to an oil gauge'for automobiles.

It is v,an object ofthe `invention VVto4 pro- .vi'dean oil gauge of this character which is foolproof that-it isi-capable of indicating the exact quantity of oil within the crank case of the engine withoutV providingmeans for disposing the oil within the gaugeabove the vlevel of the oil within the crank case of the engine.

It is another object of the invention to provide a gauge of this character wherein the level of the oil within the gauge corresponds to the level of the oil within the of-oil mayV always be obtained.

It ismore particularly the object of the invention to provide a gauge o-ftliis charany suitable material, as it is notl necessary acter wherein the gauge may be drained and means inserted not only through the draining means, but through the conduit leading to the crank case for cleaning said conduit to remove sediment and prevent clogging.

It is a. further object of the invention'to provide a gauge of this character including a measuring rod, said rod having a cap on one end adapted to be connected to the gauge to prevent the entrance of foreign matter.

lVith these and other objects in view, the invention consists in the improved construction and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which l Figure 1 is a view in elevation of an oil gauge constructed in accordance with an embodiment of the invention,

Figure 2 is alongitudinal sectional view, and

Figure 3 is a view in elevation of the measuring rod and cap.

Referring to the drawings, 5 designates 'a tubular. member which `forms the body of the gauge. This member may be made 'of that it be transparent. The upper end 6 of the tubular member is exteriorly thread'- 011. GAUGE. f f 1 cent the bottom of the cock having a valve 13 adapted seriaiiro. 434,476-

The cap! 1s interiorly threadedand provided with substantially:opposed' openings .9 I.and lO7 'the -fopening '9 being1smallerf in:y diameter thanthe openi1.1;'. 11'l0...`v` i thel opening l'O,`t' he opposite end `of the conduit leading tol and extending through the wall of the crank case D lcrank case so as to receive the oil atl the Vlowest possible point.. In tliis'way, l and into the vtubular member `5 and extends upwardly in the tubular member until it reaches a levelcorresponding to the levelof the oilzwithinfthe crank case.V A pet cock. 9, said pet l2a is threaded in the opening l to be operated to permit draining of the tubular member as well lasthe conduit 1l. portant feature of the pet cock is that when the valve is disposed in lits open position, it cooperates with the opening l0 to provide an` unobstructed passage through the conduit ll to permit Ythe insertion of a piece of i l wire V`or brush for the purpose of cleaningl not onlyV the lower portion of the tubular member', but the conduit to remove sedi-l ment and prevent the conduit as well as the tubular member from lclogging and interfering with the accuracy of the gauge in addition to providing another means for draining the crank case. i

In order to vascertain the quantity of oil within the crank case, a novel form Aof measuring rod 14C isv provided, the lower end portion of which is enlarged and pro-vided with a series of markings l5 adapted to in` dicate the level of the oil. c These markings are designated high, medium and low. The upper end 16 ofthe rod is connected toa `cap 17, said cap being internally threaded:

riphery of the cap 17 is `mit the operator to readily apply and remove the same.'V Through the medium of the cap, the measuring rod is suspended centrally ofV the'tubular member 5, the enlarged portion ofthe rod terminating in spaced relationv to the cap 8 and below the lower end of the tubular member;

The tubular member may be located at any convenient point adj acent the drivers seat, for instance, it may be disposed or connectoil passes through, 'the conduit Another iml' l A spegication of:tankersilaria-.11%..y -ZPatentedF-ebi 21,1922; 'I Application Yfiled July 13, 1921. i i

'i .Conduit 11,' has astma-,12' threaded nf ed to the dash board or adjacent thefront of the drivers seat, as the conduit 1K1 may be made in Various lengths. To ascertain the quantity of oil Within the crank case, it is only necessary to rotate the cap 17 so as to. disconnect the rod from the tubular member 5. As the enlarged portion of the rod is disposed Within theoil, thelevel of the oil will be accurately registeredfon the enlarged portion so that the operator can tell the quantity of oil by the portion of the rod coated withV oil.

From the foregoing it will be readilyseen thatthis invention provides a novel form of oil gauge Whichv in vievv of its simplicity may be readily applied to the crank case of any type of automobile and wherein the quan/- tity of oil may be ascertained in the most practical manner. In addition to this, it provides means for cleaning the lower portion of the gauge so as to prevent sediment from interfering' With the passage ofoil f through the conduit and into the gauge.

Furthermore, the gauge Will last indefinitely as the tubular member 5 can be constructed of metal.

What is claimed is Y -An oil gauge of the character described comprising a socket member having opposed ports 1n its side Wall, an outlet member d1s.
